EDWARD J". VON PEIN, OF DA YTO N, OHIO, ASSIGNOR TO THE NATIONAL CASH REGISTER COMPANY, OF DAYTON, OHIO, A CORPORATION OF OHIO, (INCORPORATED IN 1906.)

. .C ASH-REGISTER.

To all whom it may concern:

Be it known that I, EDWARD J. VON PEIN, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cash-Registers, of which I declare the following to be a full, clear, and exact description.

This invention relates to improvements in cash registers, accounting machines, and the like and more particularly to those machines in which independent cash receptacles are provided for the respective clerks for keeping their cash separate so that the responsibility of mistakes and shortages may be placed on the proper clerk and also to prevent misappropriation by one clerk of the cash in charge of another.

Cash registers having a plurality of cash drawers are usually so constructed that access can be had to the drawer by depressing a single key to predetermine which drawer shall be opened at a subsequent operation of the machine. Upon operation of the machine the selected drawer is released and records of one form or another are made by the machine in a record retaining device to show which drawer was opened, the nature and amount of the transaction, etc. Indicash register money in charge of another cators as well as different toned bells are usually provided to indicate to the various clerks and the proprietor which drawer has been opened and enables each clerk to tell whether his drawer is wrongfully opened by another clerk.

The reason for having a number of cash drawers attached to the cash register is to give a separate receptacle for each attendant, thereby enabling the proprietor to place individual responsibility forerrors and shortages and also to prevent one attendant from fraudulently withdrawing from the attendant. The proprietor is able to learn whether the proper amount is in each attendants receptacle by comparing the cash.

in the drawer with the records made in the machine of the various transactions registered. It is possible, however, for one clerk to open the cash drawer of another attendant when no one is present to detect his wrong doing by merely pressing the other clerks key, the clerks keys usually bearing characters, such as initials, to indicate which drawer is controlled by each key and which Specification of Letters Patent.

be discovered by the proprietor on comparing the cash in the drawer with the records in'the machine.

The main object of this invention is to eliminate as far as possible the opening by one clerk or cashier of the drawer in charge of another by improving the construction of the means controlling the opening of the drawers. In the illustrative form shown in the accompanying drawings the object of the invention is accomplished by providing means compelling the operation of a plurality of special keys in combinations, the

keys being designed to control in certain combinations only the opening of the drawers. ,The drawer of each clerk is controlled by the operation of keys included in a certain corresponding combination, and as each clerk is to know only the combination for opening his individual drawer, one clerk cannot readily open the drawer of another. A plurality of detent plates are provided in the particular embodiment shown, one for each combination, and each of these detent plates can be moved only by the operation of keys of a corresponding combination. One of the keys in each combination is in the em.- bodiment shown. to control the extent of movement of a releasing means for thedrawer while the last key operated in the' combination, which may also be the key con trolling the movement of" the releasing forms of detents for locking the operated the stud 24 with the shoulder 25 on the arm 26 rocks the arm 26, shaft 16 and the arm 15 counter clockwise and in this way extension 14 on the arm 15 is drawn out of engagement with the disk 12 to permit operation of the machine. I

The cash drawers 28 (Figs. 3 and 4) which in the embodiment are shown arranged in one vertical row are held shut by their catches 29 which have formed on their rear ends hooks 31 engaging drawer catch plates 32' fastened to the rear of the machine. It will readily .be seen that in order to release anypne of the desired drawers all that is necessary is to push the end of its drawer catch 29 down so that the hook 31' will disengage the plate 32. In the operation of the machine this is'done by the catch trip lever 33 in the following manner. When the keys in the combination are depressed against the tension of their springs 34 and the register operated, a segment 35 (Fig. 1) is differentially positioned dependent upon which of the depressed keysis engaged by' a trip pawl 36 of the latch 37 carried by the segment. The manner in -which this is done is well known in the art and is fully explained in the Cleal and Reinhard patent above mentioned and ref erence may be had to this patent for a full a 39 fast to a shaft 41, to which is also fastened a bevel gear 401 and this bevel gear 401 meshes with a bevel gear 40 (Fig. 3).

' This latter gear is splined on a shaft 42 to drawer fingers 45 (Fig. ,14), one for each drawer and .these are so positioned that when the segment 35 is stopped by a certain one of the keys in a combination, one of the drawer fingers 45 will be under the drawer catch trip lever 33 for the drawer that corresponds to the combination of keys depressed.

The finger shaft is next raised so that the finger 45 for thedrawer that is to be opened and which has been adjusted under its drawer catch lever will rock the appropriate lever 33 for the drawer to be selected about its pivot 35 forcing the opposite end of the leverdown against the end of the catch 29, and disengaging it from the plate 32. The drawer is then ejected from the cabinet in the usual manner by a spring 46 which collar 54 secured to the shaft 42.

is carried on the rear wall of the drawer and is compressed against the plate 32 when the drawer is given its full inward stroke.

The finger shaft 44 can be raised by any one of a number of different forms of lifting mechanism. In Figs. 1 and 3 of the drawings there is shown in'dotted lines a conventional device comprising a pitman and a cam 51,'the cam being mounted on and near the right end of a drive shaft 52. The upper end ofthe pitman has a hook which engages over the drive shaft 52 and carries at its side a roller resting on the cam 51 as shown. The enlarged lower end 47 of the pitman 50 has (Fig. 3) a vertical slot 48 through which the end of a lever 56 passes. The other end of this lever is pivoted to the frame of the machine while the lever intermediate its ends engages a The cam 51 is rigidly fastened to the drive shaft 52 and as the shaft is turned during an operation of the'machine the pitman 50 will lift the lever 56 and therefore through collar 54 the shaft 44 against the action of the spring coiled about the shaft and compressed between the collar 54 and a flange 49 on the frame 49 thereby releasing the drawer that is to be opened.

The segment gear 35 meshes also with a gear 57 loosely mounted on the shaft 11. This gear 57 meshes with a pinion wheel 58 rigidly mounted on the side of an indi cator 59 loosely mounted on a transverse shaft 61. The indicator bears initials or numbers corresponding to the drawers to indicate which drawer has been last opened, and it is clear that when the segment gear 35 is differentially moved the indicator will be given a like extent of movement.

All of the mechanism mentioned so far is old in the art and needs no more detailed description. The reason it has been covered .to such extent is because some explanation is thought desirable to make the following description of the new mechanism more easily understood.

The improvement consists of means compelling the operation of the keys 1 to 9 in certain combinations to select the drawer to be opened and to unlock the machine, thus making it harder for one clerk or cashier to gain access to anothers drawer. This is accomplished in the form shown by the employment of a plurality of detent plates 62 (Figs. 1, and 5 to 12 inclusive) any one of which is operated by keys in a corresponding combination only to move the plates 18 in order to unlock the machine so that the latter may be operated. The extent of movement of the differential segment gear 35 when the machine is operated is determined by one of the keys in the combination being engaged by the trip pawls 36 for the latch 37 tripping the latter to allow the driver 7 5 There is one of these detents for each, combination and as there are nine keys, one for each drawer, nme comblnatlons can be employed. Five of these combination de-' tents are preferably arranged to the left of the plate 18 on the left side of the side frame 17 and four of them are mounted to the right of the plates 18 and on the right side of the frame supporting'the keys. They are slidably mounted on the pins 20 in the same manner as are the plates 18, having the'slots 53 and the elongated notches 64 through which the pins 20 pass similar to those described above as in the plates 18. A pin 65 on each plate 18 normally passes through the center of slots 66 in all the plates arranged along the side of the respective plates 18.

The keys as usual carry pins 67, but these pins project from both sides of the key shanks and pass over the forward edges of all of combination detents. When the first key in any combination, there bein two keys for each combination in the pre erre'd form, is depressed, one of its pins 67 engages an inclined edge 68 of a projection 69 on the corresponding combination detent and raises the detentuntil the lower end of its slot 66 is just in contact with the pin 65. Such movement of the detent brings an inclined edge 70 of a projection 71, which is shown narrower than the projection 69, into the path of the pin of the second key in the combination of which the key depressed is the first. Depression of this latter key through the engagement'of its pin 67 with the inclined edge 70 raises the combination detent one step further and as the lower end of the slot 66 is then in engagement with the pin 65 on the plate 18, the plates 18 and the combination detent are moved together during this last step of movement of the latter. As hereinbefore described the final increment of movement of the plates 18 through the engagement of the stud 24 with the shoulder 25 on the arm 26 rocks the shaft 16 counter-clockwise to lower the locking, arm 15 out of engagement with the disk 12 so that the machine may be operated. When the second key is depressed the ends of the rectangular shaped projections 72 which are on the operated detent and are normally out of the path of the pins on the keys are moved under the pins not belonging to the combination shifting the moved plate, so that the keys not included in this particular combination are locked against operation.

It is understood, of course, that the projections 69 and 71 on each combination, de-

shown in Fig. 1 is 37 as the 3 key and subsequently the 7 key are depressed to operate the same. Depression of the 3 key through the engagement of the pin 67 with the inclined edge 68 of the projection 69 of the 37 combination detent, raises the detent so that the lower inclined edge 70 of the projection 71 may be brought into the path of the pin on the 7 key which is. the other key in the combination to be depressed. Operation of this latter key raises the detent still further to raise the plates 18 and cause the latter upon the last part of their movement to rock the arm 26 and thereby unlock the machine. It can readily be seen that 63 is the combination for moving the detent shown in Fig. 5, as the 6 and then the 3 key must be depressed to operate the detent, and that 26 is the combination for operating the detent shown in Fig. 6, as the 2 key and then the 6 key must be operated to actuate the detent. vIn a like manner it is obvious that the combinations of keys for movin the combination detents shown in Figs. 8,

9, 10, 11 and 12 are 49, 58, 95, 15, 78 and 81 respectively. If as shown in these figures the combination detents are so constructed that the nine projections 69 are adapted to be engaged respectively by different keys only the selected detent would be raised upon operation of the first key in the combination, while the second key would raise this detent still further and give another'detent, the inclined portion 68 of whose projection 69 was in the path of the pin on the second key, one extent of movement. With the projections 64: arranged differently it is clear that the number of plates actuated would be dependent upon the arrangement of the projections 67 and the keys operated.

, In those combinations which operate thefour combination detents on the right side o f.the keys the lower key in each combinat1on determines which drawer shall be opened. This is true as the lowest key is the first to be engaged by the .trip pawl 36 to.

disconnect the latch 37 from the driving segment 75, the operation of the segment and the latch being fully described in the aforesaid Letters Patent granted to J. P. Cleal and .F. A. Reinhard. As the lower key determines the extent of movement of the segment gear 35 in operations in which the 'ma the left side of .the

To this end the five combination detents on side frame 17, which are the combination detents controlling" the unlocking of the machine when one of the drawers corresponding to the five upper positions of the-segment is to be opened, are provided with V-.shaped members 76 as bers are pivoted on pins 77 to these combination detents and each is so positioned on its supporting detent that the end of the forward arm.78 of the V-shaped member is in the path of the lower key in the correspond ing combination so that depression of this key rocks the member about its pivotal centerand the inclined edge SOpf the reararm 79 of the member is thereby held while the key is retained depressed the path of the trip pawl 36, the upper end .of the trip pawl being provided with a horizontally extending 7 arm 79 of the member opening of the drawer,

flange 85 which extends of the combination detents carrying these members'78. When the segment gear 35 is actuated, the trip pawl 36 engages only the rocked by the depressed key but the arm 79 deflects the trip pawl 36 from its normal course about the end of the key operating the V-shaped memher and without being obstructed by the lower end of the depressed key-"as the trip pawl is allowed to be pressed rearward about its pivot 84 against the action of its.

spring 81. As the trip pawl 36 passes out of engagement with the arm 79 and around the lowermost depressed key its .spring 8 1 pushes it forward to normal position so'that' it will engage the end of the key and thereby trip the latch 37. Leaf springs 82 project from the members 78 between their arms their combination detents and serve to restore the members to initial position after the depressed combination keys are returned outward to normal position upon being re leased and to normally hold'the members out of the path of the arms 79 as shown.

With the fingers 45 helically arranged on 44 as is usual in the art they the finger shaft drawer to be opened is in the same relative position in the limiting the extent of movement of the seg-' ment gear 35 and thereby controlling the the fingers 45 so arranged that one key of prevent the lower keys in the across the rear edges upper depressed,

and, engage pins 83. on)

tier of drawers that the key not in the same every combination is readily ascertained by all of. the clerks, a clerk could press the known key of another clerks combination, which bears the same relation to the other keys as does the drawer opened by such clerk to the other drawers, and then by depressing the other keys until the other key of the combination is found, open the drawer assigned to the other clerk. To eliminate as far as practical the possibility of one clerk ascertaininganother combination and opening the drawer of such other clerk the fingers 45 in the preferred form shown have been staggered on the finger shaft so that the drawer to be opened is relative position in the row of drawers that its controlling key in the combination is in the bank.

For exam le in the preferred form, the finger 45 Fig. 14) is the fourth finger from the top of the shaft and is for opening the fourth drawer from the top, and its sitions in is inthebank. With sired so thafi the relationship with angular position is 252 from the position in which it will engage, when lifted, the drawer catch trip lever 33 for the fourth drawer. As one'step of movement ofthe segment gear 35 rotates thefinger shaft 36 it is evident that the segment gear 35 moves 'f'seven steps before the finger 45 which is 252 from operating position is in operative its respective drawer catch trip lever 33, and therefore as the key stops movement of the segment gear 35 at' the end of its seventh step of movement, the combination'37 (Fig. 1) controls the opening of the fourth drawer in thevtier. The finger 45 is the seventh finger from the top of the shaft 44 and is for unlocking the seventh drawer and is 144 from the position in which it will engage, when raised,the drawer catch trip lever 33 for the seventh drawer and therefore the combination 63 (Fig. 5) controls the opening of the seventh drawer. In a like'manner the finger45 is the third from the top of shaft 44 and eight steps of movement, the is the fifth from the top of shaft 6 steps of movement, and the is the sixth from the top of shaft 5 steps of movement from their powhich they when raised will engage their respective trip levers 33 and the combinations 26, 49 and 58 (Figs. 6, 7 and 8 respectively) control the opening of third, fifth and sixth drawers respectively. The

10, and 112 respectively) which efiect the positioning of fingers 45 45 45 and 45 respectively eighth, second, first and ninth from the top'of shaft 44, control in a similar manner'the opening of the eighth, second, first and ninth drawers respectively. Of course it is obvious that the arrangement of these fingers 45 can be varied as decombinations shown can ated positions is shown in Fig. 13 and this.

initial of the clerk to whom the drawer is assigned.

The means for locking the keys in opermeans will now be described. Nine locking dogs '90 are pivotally mounted by pins 89 on aplate 91. The plate 91 is slidably mountedat the left of the last combination detent to the left of the keys, on the pins 20 which pass into the slots 92 in the plate. The locking dogs 90 are bell crank in form and their forward arms form hooks and have inclined faces 93 normally in the projecting The other arms ofv the dogs are provided with flanges 94 which are normally in engagement with the rear edge of the plate 91 and so held in path of the end of the pins 67 "that position by also being in engagement with the periphery of a segment plate 95.

so that'the upper wall of the recess 104 be '45 low the inclined face 93 will engage over:

a clined Atits rear end the segment plate 95 is bifurcated and straddles the transverse shaft 96 and near its periphery carries apin 97 passing into a slot 98 formed in a pro ection 99 of the plate 91. A spring 100 which is under tension between a pin 101 on a projection 99 and a pin 102 on the plate 95 tends to pull the plate 95 forward to keep the locking dogs in normal position. When a key is depressed its pin -67 engages the inclined face 93 of its locking dog and rocks the latter counter-clockwise, as viewed in Fig. 13, and as the pin passes oif the inface the plate 95, through the spring 100, restores the detent to normal position the pin 67 on the key to retain the key in c depressed position. In'this manner it will be seen that as each key is depressed its corresponding locking dog will'lock it in depressed position without operating the other dogs so that two keys can be operated in the bank during the same operation of the machine.

Near the end of the operation of the machine the-shaft 96 is rocked upward past thenormal position (shown; in Fig. 13) as described in the above mentioned Cleal and Reinhard patent and an arm 105 fast to the shaft is thereby brought into engagement with an anti-friction roller 106 mounted on the segment plate 95 to rock the plates 95 and 91 as a unit, they being connected, as described by the pin 97 on the plate 95. As the locking dogs 90 are held by the plate 95 from moving relatively to the plate 91 upon movea 1 V f 1,284,238;

ment of the plates 91 and 95 it can readily be seen that the recesses 104 of the dogs in locking'relationship with the keys will be carried out of engagement with the pins on the depressed keys so as to permit the springs 34 coiled about the key shanks to force the keys outward to their normal position. After the keys are released the plates .95 and 91 are returned by a spring 111 attached at one end to the frame and at the other to the plate 95, to lower and normal positions.

The plate 91and' also, through the pin 97, the plate 95 may be moved upward to re lease any key depressed in error before the actuation of the operating mechanism by rocking a shaft 108 carrying an arm 109 clockwise as the lower end of the plate is in engagement with this arm. The shaft 108 is connected with a special manipulative arm or device but asthis key releasing mechanism is old in the art it need notbe described in detail herein. H

So far as applicant is aware there has been prior to this no drawer releasing mechanism controlled by manipulative means operable' only in combinations and it is intended that the claims included herein should cover all the various forms of'embodiment of which the rinvention is suscep- 95 tible. It is apparent that any particular number of drawers is not essential to the successful operation of the improvement and also that any number of combination keys may be employed as desired.

While the form of mechanism herein shown and described is admirably adapted to fulfil the objects primarily stated, it is to be understood that it is not intended to confine the invention to the oneform of 105 embodiment shown and described herein, as it is susceptible of embodiment in various forms, all coming within the scope of the a claims which follow.
